1. the sum of integers p and q is modeled on a number line, where /p//. in each box, write p, q, or p+q. then write an addition equation using integers that could represent p, q and p+q.
2. show how the model in problem 1 would change if /p/> /q/. draw the model, labeling p, q and p+q. the write an addition equation using integers that could represent p, q and p+q
